GLUT includes a number of routines for generating easily recognizable 3D
geometric objects. These routines reflect functionality available in the
aux toolkit described in the OpenGL Programmer\'s Guide and are included
in GLUT to allow the construction of simple GLUT programs that render
recognizable objects. These routines can be implemented as pure OpenGL
rendering routines. The routines do not generate display lists for the
objects they create. The routines generate normals appropriate for lighting
but do not generate texture coordinates (except for the teapot).

A cube centered at the modeling coordinates origin with sides of the
given length.

Dodecahedron

A dodecahedron (12-sided regular solid) centered at the modeling
coordinates origin with a radius of sqrt 3.

Icosahedron

A icosahedron (20-sided regular solid) centered at the modeling
coordinates origin with a radius of 1.0.

Octahedron

Render a solid octahedron (8-sided regular solid) centered at the
modeling coordinates origin with a radius of 1.0.

Tetrahedron

Render a solid tetrahedron (4-sided regular solid) centered at the
modeling coordinates origin with a radius of sqrt 3.

RhombicDodecahedron

(freeglut only) A rhombic dodecahedron whose corners are at most a
distance of one from the origin. The rhombic dodecahedron has faces
which are identical rhombi, but which have some vertices at which three
faces meet and some vertices at which four faces meet. The length of
each side is (sqrt 3)/2. Vertices at which four faces meet are found
at (0, 0, +/-1) and (+/-(sqrt 2)/2, +/-(sqrt 2)/2, 0).

A sphere centered at the modeling coordinates origin of the specified
radius. The sphere is subdivided around the Z axis into slices
(similar to lines of longitude) and along the Z axis into stacks
(similar to lines of latitude).

(freeglut only) A cylinder oriented along the Z axis. The base of the
cylinder is placed at Z = 0, and the top at Z = the given height. The
cylinder is subdivided around the Z axis into slices, and along the Z
axis into stacks.

A torus (doughnut) centered at the modeling coordinates origin
whose axis is aligned with the Z axis. The torus is described by its
inner and outer radius, the number of sides for each radial section,
and the number of radial divisions (rings).
